Priorities USA Action said it won’t back Democrats who vote or support Kavanaugh, whose nomination was in turmoil amid allegations of sexual assault. Priorities hadn’t spent any money to help Bredesen and will now forgo that possibility in the remaining weeks before the midterms.

“We haven't been spending there and any option to is now off the table,” Priorities spokesman Josh Schwerin told The Hill.

Bredesen announced on Friday that he supports the confirmation of Kavanaugh, while also condemning the treatment of Christine Blasey Ford, who testified late last month that Kavanaugh sexually assaulted her in high school, which he has vehemently denied.

“While the subsequent events make it a much closer call, and I am missing key pieces of information that a sitting Senator has, I’m still a ‘yes,’” Bredesen said in a Friday statement.

While Priorities won’t spend on behalf of the Tennessee Democrat, Bredesen has already gotten major help from other Democratic outside groups that have spent millions to elevate him, including Senate Majority PAC (SMP) and Majority Forward.

Manchin is up for reelection in a state that voted for Trump by more than 40 points. He's running against West Virginia Attorney General Patrick Morrisey (R), though polls show Manchin comfortably ahead.

While Priorities is stepping away, SMP told the Washington Examiner on Friday that they’ll continue to support both Bredesen and Manchin’s Senate bids.

"Senate Majority PAC supports Phil Bredesen and Joe Manchin. They are the only candidates with an independent record of getting results for Tennessee and West Virginia," SMP spokesman Chris Hayden told the Examiner. "They're both winning these races because of their record."
